I have used the same card for months.
And disabled the "reset counter on cardswap" option.
Anyway this picture session went from 197canon/img_9741 -> 200canon/img_0091
without swapping card so what you mention is not the case.

The only case I had a disruption in the numbering of pics (apart
deleting a bunch of data) was when I used the same cards in different
bodies. I have an EOS30d and a G3 and it's quite easy to confuse the order.

Do you know if the camera counter is at say '192-9256' and you insert a card
that have a picture at the same number position. Will it overwrite that picture
when you take one with the camera?
If it will overwrite in this situation.. it's certainly a bad thing..

1. Canon specifically mention the 99 thing (check the manual for exact
wording).
2. With reset counter off, you should never go backwards in numbering.
If numbers on the card are lower than last pic taken, camera should skip
to next higher camera number. If number on card is higher than last pic
taken, camera internal counter will skip, so you will not overwrite a
picture on card.

I've not reached as high a number as mentioned here, but it looks like
you've reached the number limit and numbering is rolling over although
it's not clear if you mean you took a whole bunch of pics and the last
number was 91, did you not get 0001 etc.?, although it seems the folder
number isn't getting reset.
I agree, figuring out the canon algorithm is quite a challenge.

We fucked up, but the damage description is in the manual

I did get 200canon/img_0001.jpg but img_9901-img_0000 doesn't occour.
The last pic was 200canon/img_0091.jpg in that round.

Well I think it's a case of sloppy programming. Though camera don't screw
up anything important.
